Specification of Letters Patent.

Patented July 13, 1915.

Original application filed July 12, 1911, Serial No. 638,078. Divided and. this application filed November 3,

17b all whom it may concern Be it known that I, FREDERICK L. Knrr- LER, a citizen of the United States, residing at Berlin, Germany, have invented a certain new and useful Improvement in Transparent-Tile Structures,of which the following is a specification.

My invention relates to transparent tile structures, particularly such as are intended to be used for vertical or inclined partitions, roofs and the like.

It is illustrated in the accompanying drawings, wherein Figure 1 is a vertical cross section showing various forms of tile, and Fig. 2 1s a side elevation of Fig. 1 looking toward it from the right-hand side of the sheet.

Like parts are indicated by the same letter in both of the figures.

A, A are the frame pieces which surround the opening to be filled by the transparent tile structure; B is a unit smoothed on both faces; B a unit corrugated on both faces at B 13 is a unit corrugated on one face and curved on the other at B B is a unit corrugated on one face and flat on the other as indicated at B. Each unit is provided about its periphery with a rim C preferably provided with two outwardly converging curved surfaces C C These rims are preferably in substantial contact with the opposed rim of the adjacent unit so as to make an inclosed space between their edges which are recessed or grooved at D, D so as to inclose the concrete element E. Buried within this element is the reinforcement rod or wire F. These several parts are assembled as follows: The lower transparent units are supported on the frame and the vertical rods or wires are attached in position, the units being strung into place or slipped down along these vertical reinforcements. The cavities between the edges of the units and about the vertical reinforcements are now filled up with concrete. The lowe transverse reinforcement is now placed in position and the concrete built up about it in the uppermost groove of the lower units. The next set of units is now placed in position and forced downwardly until the channel between the opposed grooved edges is just filled with concrete and the process is continued until the opening is filled or the desired plate finished.

By the use of the rims with converging Serial No. 730,119.

curved surfaces I obscure the opaque memopaque grid is seen merely as a vague shadowy outline.

I have illustrated and described my invention as having a grid with two groups of reinforcing rods or wires crossing each other. In some cases, of course, a single group is suflicient and in such a case the preferred form would be that containing the horizontal reinforcing members, for these would be much easier to place in position. Where the structure is small, reinforcing rods can be dispensed with entirely.

The translucent units are substantially in contact along the margins of their two surfaces. In practice in a structure they are slightly separated as, for example, by a sheet of paper, but when this is removed they are still what I understand by the meaning of the term substantially in contact.

This application is a divisional application derived from application #688,078, filed July 12, 1911.

1 claim:

1. A structure consisting of a series of assembled translucent units substantially in contact about all their margins with opposed oppositely depressed edges, each unit pro vided with rims outwardly projecting from both sides in combination with a grid consisting of concrete filling the closed space 5 between the unit edges and reinforcing bars embedded in such concrete.

2. A structure consisting of a series of assembled translucent units substantially in contact about all their margins with opposed oppositely depressed edges, each unitprovided with rims outwardly projecting in combination with a grid consisting of con crete filling the closed space between the unit edges and reinforcing bars embedded in such concrete.

3. A structure consisting of a series of assembled translucent units substantially in contact about all their margins with opposed oppositely depressed edges, each unit lOt provided with rims outwardly projecting from both sides and each rim bounded by converging curved surfaces in combination with a grid consisting of concrete filling the closed space between the unit edges and reinforcing bars embedded in such concrete.

4:. A structure consisting of a series of assembled translucent units substantially in contact about all their margins with opposed oppositely depressed edges, each unit provided with rims outwardly projecting from both sides and each rim having outside 'curved surfaces in combination with a grid consisting of concrete filling the closed space between the unit edges and reinforcing bars embedded in such concrete.

5. A structure consisting of a series of assembled translucent units substantially in contact about all their margins with opposed oppositely depressed edges, each unit Copies of this patent may be obtained for five cents each, by addressing the Commissioner of Patents.
